reference beinO had to the accom aan ino y drawings, and to the numerals of reference marked thereon, which'form a part of this specification.

This invent-ion relates to a type of lock wherein a latch member is connected on the hinge side of a casing or frame for a door or window and has sliding relation with a casing mounted upon the door or window to latch when the door or window is swung from open to closed position. Furthermore, when the mechanisms are interlocked or latched as the door is swung to closed position, said mechanisms .areA further actuatable to draw the door or window tightly closed in its frame by exerting stress' upon the mechanisms and moving the same beyond dead center position to prevent accidental i'elease thereof. y

It is an object therefore of this invention to construct an improved type of lock wherein a latch member is mounted on the hinge side of a frame or casing and vacts automatically to latch with mechanisms `mounted on the door or window when the same is swimg into closed position, and with said mechanisms actuatable by a suitable handle for the purpose to tension said latch membei' to draw the door tightly closed, and also actuatable to positively release said mechaiiisms from the latch member to permit Y opening of the door.

It is also an object of this invention to construct a locking device comprising a slidable latch member adapted to interlock with an adjustable mechanism acting, when adjusted in one direction, to tension the Y latch member and said mechanism to hold the two tightly interloclred with one an-` other, and, when actuated in the oppositeceive the latch interlocking automatically therewith. f

It is also an object of this invention to construct a locking device adjustable at the hinge side of a door and its frame comprising means rigidly secured on the frame, andv having telesooping engagement with mechanisms secured upon the door, and with said means and mechanisms acting automatically tofinterlock or latch with one another when the dooi` is swung from open to closed position yand capable of further actuation to stress said means and mechanisms to draw the door tightly closed in the frame.

It is furthermore an important object of this invention to construct an adjustable lock adapted for connectionon the inside of a door or window, so constructed as to insure positive alinement of the parts irref spective of sagging of the door in its frame, acting automatically to latch when the door is swung .into closed position, and capable of actuation to draw the door tightly closed in its frame after the same has been swungl into closed position.

It is finallyan object of this invention to construct an improved type of lock, simple in construction and operation, and cheap to manufacture. I Y i The invention illustrated in the drawings and hereinafter more fully described. Y

noted by the reference numeral A4, having, lateral attaching fianges 5, integral there with, and with a cover plate 6, adaptedto be connected to said attaching flanges when the casing and cover plate are mounted upon the door by means of screws extending through holes or apertures 7. Secured at one end of the casing 4, are a pair of arms 8, affording a yoke for attachment therein of a tubular member 9, ly means of a pintle 10. Slidably mounted within said tubular member 9, is a long rod 11, which, at its inner end within said tubular member 9, has adjustably threaded thereinto a latch member 12, extendingk slidably through a guiding or alining collar 12a, and at its other end said rod 11, is connected by means of a pintle 13, to a hinge bracket 14, secured upon the frame 2. At the outer end of thetub-ular member 9, a collar 15, is threaded thereon,

. the detail of which is shown in Fig. 12, and

threaded through a boss formed therein, is a clamping screw 16, having an actuating head 17, whereby said screw maybe threaded inwardly to clamp tightly against the inner telescoping rod 11, to prevent movement thereof `in the tubular telescoping member 9. y

Slidably mounted withinsaid casing 4, against the cover plate G, thereof, is a T- shaped slide plate 18, having at its inner end a long tongue extension 19, and with beveled abutments 20, formed on each side of said tongue extension. Slidably mounted above said plate 18, is a long tilting latch plate 21, at its rear end having a rectangular slot 22, the rear end of which is beveled Aadapted for engagement with the forward end of the latch member 12, and at its other provided Ywith an enlarged curved recess 23, within which is rotatably mounted an eccentric 24, secured upon anl actuating handle 25, which is journaled transversely through the casing 4, andthe cover plate 6.

Formed on the outer surface of said plate 21, at the side thereof, are a pair of inclined abutments 2G, adapted for coaction with the beveled portions20, of said slide plate 18, to slide thereon and cause tilting of the plate 21.. A leaf spring 27, is secured on the inner surface of the .wall of the casing 4, and bears outwardly against the rear surface of the plate 21, to close the same normally flat against the plate 18, and parallel to the to thrust said forked plate 28, rearwardlyin the casing thus compressing said springs 31. Another crank 33, is also formed on the handle 25, disposed adjacent the cover plate 6, adapted to actuate the slide plate 18, which, due to the fact that the head or extension thereof contacts the abutments 29,

of said plate 28, acts to compress the springs 31, to resist movement of the handle.

The operation is as follows:

The parts as shown in illustration in Figs. 2,3, 4, and 5, are in normal or neutral position, that is, with the latch member 12, loosely engaged with 'thetiltable slide plate 21. Then lit vis desiredl to lock the door closed in its frame, the handle'25, is rotated clockwise. or to the right referring .to the front view of the device shown in Fig. 3, whereby the eccentric 24, acts to thrust the slideplate 21, forwardly so that the beveled edge of the slot 22, therein, is drawn against the beveled hooked end of the latch 12, and as said eccentric'24, is rotated past the dead center position, a tension is exerted upon the parts of the mechanism to hold the same tightly engaged with one another andv with the door, ofcourse, drawn tightly closed in the frame, Furthermore, the crank 33, thrusts the plate 18, rearwardly and with it the plate 28, thereby compressing the. springs` 31, which, when the lock is released, aid in returning theparts to normal or neutral position. VVhen a releasing movement takes place, the handle, ,of course, first .passes into neutral position whereupon lthe parts assume the position shown in Figs, 2 to inclusive, and with a continued reverse rotation of thehandle,.that is, counter-clockwise or to the left :referring ,tothev front view of the device shown in- Fig. 3, the respective cranks 32 and 33, Dn saidA handle act to thrust the respective plates 1.8 and 28, rearwardly within the casing, the plate 28 act,- ing to compress the springs 31, vthus resisting the movement of the handle.

On-the other hand. rearward movement of the plate 18, causes theA beveled edges or portions 20, thereof,to engage-beneath the abutments 2G, on said tilting lever 21, thereby tilting the same into .the position shown in:

Fig. 8 and lifting the slot 22, entirely away from the end ,of the latch member 12, so that when the door is swung open, said latch inember may be withdrawn from the casing 4, as said elements 9 andV ll, are drawn apart, and with the latch l2, of course, being drawn inwardly into the tubular member 9. Of course, release of the handle 25, after the door has been swung partly open so as to throw the latch l2, out of Vpossible engagement with the slot 22, permits the parts to return to normal under the stress of the leaf spring 27, which throws said plate 21, outwardly into parallel relation with the casing, and, of course, the springs 31,-act to return the handle to upright or neutral po# sition.

If the door is swung into closed position, the latch l2, is projected into the rear end of the casing fl, elevating the end of the plate 21, against the stress of the leaf spring '27, and latching in the slot 22, whereupon the handle is rotated in a direction to draw the plate 2l, tightly into engagement with the end of said latch member to draw the door tightly closed and to maintain the same locked in the frame. It is thus apparent that the springs 3l, are compressed whenever t-he handle is rotated from neutral position either into release or into locking position, due to the fact that said plate 28, is struck rearwardly when the handle is thrown into locking position by the plate 18, to cause compression of the springs, and when the handle is thrown toward release position the plate 28, is thrust rearwardly by the crank 32.

lf it is desired to lock the door in an open position of adjustment as, for instance, an automobile door for ventilating purposes, the door is moved into an open position and the screw 16, threaded inwardly by means of the head 17, thus clamping the rod ll, within the tubular member 9, and preventing relative movement thereof, the door being thereby held in a rigid position. Said clamping mechanism may also be used as an auxiliary lock when the door is moved into locked closed position if so desired.

am aware that variousdetails of construction may be varied through a wide range without departing from the principles of this invention and I therefore do not purpose limiting the patent granted otherwise than necessitated by the scope of the claims.
